These are new dev builds, Devo7E without standard GUI.

HiSky is implemented satisfactorily, but I need it tested on more models than my only Q-BOT and tested for interference. If you have 2 Devos or original HiSky transmitter, please test that they don't interfere.

I just test with my V922 (HiSky) and my V252 (V2x2) it's binding perfectly and flew smooth ..

Tested with V933 (FBL80). After the old patch it took bind again. Everything else works fine.

Thanks! It was accepted and should be in nightly builds.

The bind behavior was expected - I tweaked frequency hopping algorithm and correspondence between TX id and internal protocol id.

I tested also like this :

my V922 controled by your build while my V944 controled by stock TX. Working perfectly togather :)

thanks for your work victzh, but do you have a patch based on the nightlies, or even a link to your repo?, as i use the standard ui because i have no need for the complexity of the advanced ui for my micro heli's

victzh,
Can you replace the 64bit match with 32bit math in the hisky protocol?
The 64bit math gets optimized in funky ways depending on the compiler and is not reliably built for Devo7e.
This appears to just be for generating a unique id, in which case it shoyuld be easy to use an alternative implementation.

Also, this is not ok to be in the protocol code:
#ifndef USE_FIXED_MFGID
    // Every STM32 should have 12 bytes long unique id at 0x1FFFF7E8
    u8 *stm32id = (u8*) 0x1FFFF7E8;
    printf("Manufacturer id: ");
    for (int i = 0; i < 12; ++i) {
        printf("%02X", *stm32id);
        update_lfsr(*stm32id++);
    }
    printf("\r\n");
#endif
There should be nothing processor-dependent in the protocol code. If you want a unique-id, define a new function in common_devo and access that from here

I made some changes to the hisky LFSR stuff. Hopefully I didn't break anything.

OK, I'll check it. It is hard to break - I just needed 5 byte randomized address and 4 bytes for frequency hopping sequence. As this sequence is passed explicitly during binding, it does not matter how it is generated. If these bytes random enough, it's OK.

@PhracturedBlue, I think what you've done is great. If you don't mind I will replace CRC of Model and Transmitter in SLT and V202 code with similar to what is done in HiSky.

@HappyHarry, nighlies should get this code by now, and as far as I understand they have Standard GUI as PhracturedBlue uses different compiler that can build it.

Do you confirm that the fixed HiSky and V2x2 protocol are now in the last nightly build ?

I flew outdoors 3 lipos with my V922. The connexion is solid and smooth. Reaching 50m without any problem ...

What a great news, and in the nightlies to.

Thank you very much for you commitment in the protocol area Victor :D

@SeByDocKy what do you mean by fixed V202? The repeatedly fast binding error? No, I still did not have a chance to look at it, but as it is minor and don't affect the flight you can use V202 with no other problems.

@blackmoon thanks, but all this would be impossible without much larger effort of PhracturedBlue, rbe2012, FDR, and many others.

just back from the field and another success report, an fbl80 with devo7e/deviation and an v922 with a jr dsm9x with a wl-t6 module both flying at the same time with no problems.

thanks so much for your work on this protocol victzh B)

Just to remind everybody, even the protocol work is not fully mine - I used a piece from suvsuv repo. My own reverse engineering effort for HiSky was not that advanced by the time I learned there is already working implementation that just needs finishing up.

Yes !!!! Great job :) Looking forward also SLT protocol ...
I never use it. Is it more the same than DSM2/DSMX in range performance ?
